'Cave' in the Bible
David went from there and escaped to the cave of Adullam. When his brothers and all his father's household heard, they came down to him there.
He came to the sheep pens beside the road, and a cave [was] there. Then Saul went in {to relieve himself}. Now David and his men [were] sitting in the innermost part of the cave.
So David rebuked his men with the words and did not allow them to rise against Saul. And Saul got up from the cave, and he went on his way.
Then David got up afterward and went out of the cave and called after Saul, "My lord the king!" When Saul looked after him, David knelt down [with his] face to the ground and bowed down.
Look, this day your eyes have seen that Yahweh gave you today into my hand in the cave, and some said to kill you. But {I took pity} on you and said, 'I will not stretch out my hand against my lord, because he [is] Yahweh's anointed one.'
